Application net December l, Wilt. Serial No. eoavm To all whom it may com-em Be it lmown that l, Lows 18. Stevens, a citizen of the United States, and a resident of New Britainfin thecounty of Hartford and State of Connecticut, have invented certain new and useful Improvements in Shaftldperators, of which the following is a specification.

The object of this invention is to produce an operating mechanism' for a shaft in which there is provided means forlocking the shaft in certain positions, the actuator releasing the locking mechanism.

"something of that sort, and

An embodiment of the invention is illustrated in the drawings, in which- Figure 1 is a longitudinal central section of the invention. Fig. 2 is a view lookingfrom the left of Fig. 1. Fig. 3 is a sectional View on the line 33 of Fig. l. lEi 4: is a view of the operating parts detache Referring to the drawings, 0: denotes what may be termed the driving shaft, and b the driven shaft. These two parts as shown are arranged in am'al alinement. 4

c is a housing which is adapted to'he secured in place in or against a casing or within .this

housing there'is located a driving-mocha which; fit pm 5, 5, carried Toy a coniiecton 41o nism which connects the driving and driven shafts and transmits the motion of one to the other, the housing being closed hy a cap 0?. X I

A spring 10 wra p ed around the shaft a has hooked ends lg ing back of the studs 7, 7, forcing the connector laterally so as to hold the lug 15in the slot 16. The housing 0 and the cap a? provide bearings for the shafts a and h, and the shaft a is conveniently squared or given other regular form ii -order that the operat 1ng handle e can he fitted to-it. Upon'the rotation of the handle and the shaft one end of the slot 9 in the plate 8 will engage one of the studs 7 and move the connector 6 laterally to withdraw the lug 15 from the groove 16 inithe housin and the driven shaft?) can then he turne until the lug 15 comes into registering position with the groove 16, when the spring 10 will move the connector 6 and position the lug in the groove.
